Runtime error: Attempting to get a value of undef. var.

In my installer, I get the error:
- Runtime error in install: Attempting to get value of undefined variable.

The strange thing is, that the error is displayed after the script calls "Terminate Install" command.

Do you have any hint, where could be the problem? I am using some persistant variables in the script - it shouldn't make any difference, but this is the only thing that I thought could be related to the issue (since installer is saving persistant variables after closing.

Best regards
Andrej.

The timing seems strange!

Did you try running the script in the debugger to see what happens there?

Hello,

I agree - timing is really strange.

I did check with debugger, and it showed me that the error is displayed after calling "Terminate Install" - after this the install should just terminate, but instead it shows the error.

Got a minimum script to reproduce this error?

Hello,

I upgraded IA to 6.22, and first tests show that the issue might be resolved with this version.

When I checked the release notes, I suspect the following bugfix to be involved in the issue:

* Using the special variable $NEWLINE$ inside values of persistent variables caused loss of saved setup information during restart of setup. These persistent variables are now safely saved.

I had a persistent variable with $NEWLINE$ in the value.
